These vitamins are acting as co-factors, which help the body metabolize carbohydrates, protein, and fats. • In addition, these berries contain good amount of minerals like potassium, manganese, copper, iron and zinc. Potassium is an important component of cell and body fluids that helps control heart rate and blood pressure.

Iron is required for red blood cell formation, and Copper is required in the production of red blood cells.
